Answer 3

TheWh¡teCat 🇧🇬 Thank you for your answer, it is working.
But in example below function parameters are empty. What is difference between example and right task's code.

Example code:
def decor(func):
def wrap():
print("============")
func()
print("============")
return wrap

@decor
def print_text():
print("Hello world!")

print_text();

Answer 4

Lyapunov Alexander , read about decorators carefully. When you have parameters (when there's a part of the result which needs to be flexible), you call the decorator function with 1 argument (set by the input), and the inner functions also must have the parameter.
